The frame is made 11 of an L-sha ed bar r fi 9 i ff gf of the bearmg or section in which traiisverse cuts h ve been S P S own 111 lgure made on one web at spaced distances along g r 10 and,11 a front Vlews the length thereof, at which points the other formmg the bearmg member Shown 1n web of the section is bent to form the cor- 45 nor of the'frame. These'cuts mark off the Elgure 12 15 an elevatlon of connectlng parts forming the flanges 3. An additional strip used toconneot the vanes 0f the Shlltlongitudinal cut is" made betweenthe two tor for simultaneous rotation v webs of the section adjacent each transverse Figure 13 shows the connecting strip ap cut, and portions at the ends of the sides 2 5o plied to the shutter vanes are folded over at 4:, so that two sides are 10( thus shortened. This folding process is done at each corner of the shutter frame, so that the adjacent ends of the flanges may be brought together and welded together to form a rigid frame composed entirely of one piece of metal.

The bearing strips 5 for supportin the radiator vanes may be pressed out 0 one piece of metal, as shown in Figure 5, and may be attached to the side walls of the shutter frame by rivets or by welding. These bearing strips 5 may have integral tubular projections 6 thereon to form the bearings for the vanes. Flat springs 7 having a hole in each end may be placed over each pair of bearings on the bearing strip 5, which comes on one side of the frame to provide means to urge the shutter vanes toward the opposite side of the frame. The hearings 6 may have shoulders 8 formed thereon to hold the springs spaced from the strip 5.

In orderto hold the springs in place before the vanes are mounted on the bearings 6, a hook 9 may be provided integral with the strip 5 and just beneath each spring 7. An opening 10 may be provided in each spring, and when the spring is placed over the bearings, the center portion thereof may be depressed so that the hook 9 enters the opening 10 and engages itsedge and holds the central portion of the spring adjacent the strip 5, thereby urging the ends of the spring against the shutter vanes, the shoulders 8 acting as a fulcrum therefor. If desired, the bearings 6 may be slightly expanded at their ends 6 after the vanes are placed thereon to hold the vanes in place. The vanes are indicated by the numeral 20.

Figures 8, 9, 10 and 11 show a modified form of bearing member in which tubular bearings are adapted to be attached to the shutter vanes and rotatably sup orted in openings in the bearing member. he hearing member is composed of two strips 11 and 12, in which keyhole slots 13 and 14 have been formed, the keyhole slots in each stri being oppositely disposed.

e tubular bearing member 15 has an enlarged end 16 which will readily ass through the enlarged opening in the key ole slots, but is prevented from passing through the smaller part of the slot.

Bearings 15 for the vanes are inserted in the large openin s of the keyhole slots in one strip 11, and t e second strip 12 is placed thereagainst by slipping the large parts or openings of the keyhole slots over the ends 16 of the vane bearings.

Strips 11 and 12 are then moved longitudinally with respect to each other so thatthe large'openings in the keyhole slots move away from each other, thereby retaining the tubular bearing attached to the vane in the smaller portions of bot-h slots, as shown in Figure 9. With this construction the vanes may be permanently mounted between the two bearing members before the bearing strips are attached to the frame of the shutter.

Figures 12, 13 and 14 illustrate the means for pivotally connecting the shutter vanes for simultaneous rotation. This means may comprise a wire 17 bent to form a lurality of loops 18, Figure 12 showing sue loops in a single plane, and Figure 14 showing the wire bent completely over to form the loops.

Fi ure l3 s1. ws the wire 17 attached to the s utter vanes so that when the wire is reciprocated the shutter vanes are opened and closed.

Figure 15 shows a modification in which the bearing member and spring are combined. To this end a strip 19 is bent into a series of loops, each loop having an opening 19 therein to receive a bearing pin 19 attached to the shutter vane, the strip being attached to the shutter frame by riveting or welding as described abpve. In this case the loops are sufficiently large to exert compression against the shutter vanes when the vanes are mounted therebetween.

Figure 16 shows a modification of the shutter in which the vanes 20 are mounted vertically in the frame, and are wider at the bottom than at the top. In this modification the upper part of the shutter opens as soon as the vanes are rotated, but the lower part, because of the overlapping portions of the vanes, offers a restriction'to the free passage of air therethrough until the vanes are completely opened.

Figure 17 illustrates a bearing strip 21 with bearings 22 integrally formed thereon similar to the strip 5 in Figure 5, but .without the shoulder being formed on the bearings.

Figure 18 shows a bearing strip similar in outline to that shown in Figure 17, but formed out of a solid piece of metal.

Figure 19 shows a bearing 23 similar to the bearing 22 in Figure 17, but separate from the strip 24. The strip 24 may be provided with holes 25 shown in Figure 20, into which the bearings 23 may be inserted and edges 26 of the strip may then be bent down to retain the bearing on the strip. If desired the bearings may be formed on one strip of metal and cut off and inserted in the supporting strip all in the same machine as indicated in Figure 20.

Figures 21 and 22 show a similar bearing upon which the lu s 27 are formed. Holes 28 are provided in the strip 29, and when the bearings. are inserted in the holes 30, the edges 31 may be bent down so that the lugs 27 are held in the openings 28 of the stri 29.

Figures 23 and 24 show a modified orm of bearing 32 integral with the bearing strip 33. A flat portion or lug 34 of the strip 33 is cut out and bent at right angles to the stri .33, and the end of this portion or projection 34 is then pressed between suitable dies to round 01f the edges thereof to form 1 changes w ich may be made in the construction with out departing from the spirit of the invention, as for instance the transverse portion shownin Figures 23 and 26 might be cut out of the side of the strip instead of the center, and I do not therefore desire to limit myself to the embodiments shown but to interpret the invention broadly within the scope of the appended claims;

What I claim as my invention is:

' 1. In a radiator shutter having a plu rality of rotatable vanes, means to mount said vanes comprising a pair of strips of sheet metal having a plurality of projections formed thereon, means to prevent said vanes from rattling, comprising spring members between said vanes and one of said strips to urge said vanes toward the other of said strips, and means to hold said spring membersin place against said strips when said vanes are removed therefrom.
